Is there a way to access p-value from estimation?

[James Park]

_b accesses coefficient, _se accesses standard error.

But how can I access p-value?

I googled many times using many keywords but I couldn't find. This is something that is likely to have some quick way to do.

if you are talking post-estimation of some kind of regression, take a look at r(table) - e.g.,

mat li r(table)

if you want to keep using (part of) what is in r(table), save it into another matrix before you lose it

Does this help?

James, you might also want to be aware of how to refer to certain cells in the matrix r(table). It's always row, then column. In r(table), the rows are the statistics of interest (e.g. beta, se, Z-score, p-value, etc), and the p-values are in the 4th row. All the columns refer to the coefficients in the model. You might type something like:

matrix b = r(table)
scalar p_1 = b[4,1]

Thank you so much everyone!
